Some client equals YOUR machines. And no, it's not your server that has the problem, it's other people's servers. Let's say that whois on domain mrball.net results in dns entries: DNS15.REGISTER.COM 216.21.234.78 DNS16.REGISTER.COM 209.67.50.246 NIXBOX.NIXIT.CA 24.101.148.92 If you query dns15 and dns16, you will get an answer for hostnames in the mrball.net domain. However, the proprietor of the third entry does not have any real information about mrball.net. (The real whois results are just the first two). When you try to ping/lynx/whatever to www.mrball.net, you ask your nameserver for the IP address, it gets the list of authoritative DNS servers, and then asks one of them. If it finds that one says "I don't know anything about mrball.net" even though the above records indicate it _should_, then THAT is a lame server and your dns server records it in your logs. The problem is much more frequent with reverse lookups than it is with forward lookups. Blue skies...
